大家好我正在编写一个我要导出到CSV文件的脚本。
除了我想为以下数据添加列名和标题之外，一切都运行良好。
例如，变量A是2017年固定收益交易的汇总数据。我希望输出文件中的第1行可以这样读。
非常感谢任何帮助。我的代码写在下面。在此先感谢!!
#SENDS THE RESULTS TO FILE CALLED OUTFILE.TXT WHICH IS OVERWRITTEN EACH TIME SCRIPT IS RUN
sink("outfile.csv")
#SHORT-TERM PRE-REFUNDED TRADE DATA
A = MSRB[which(MSRB$Coupon.Rate >= 2 & MSRB$Year == 2017 & MSRB$Par.Traded >=500 & MSRB$Class == "PRE-REFUNDED"),]
B = MSRB[which(MSRB$Coupon.Rate >= 2 & MSRB$Year == 2017 & MSRB$Par.Traded >=1000 & MSRB$Class == "PRE-REFUNDED"),]
C = MSRB[which(MSRB$Coupon.Rate >= 2 & MSRB$Year == 2018 & MSRB$Par.Traded >=500 & MSRB$Class == "PRE-REFUNDED"),]
D = MSRB[which(MSRB$Coupon.Rate >= 2 & MSRB$Year == 2018 & MSRB$Par.Traded >=1000 & MSRB$Class == "PRE-REFUNDED"),]
E = MSRB[which(MSRB$Coupon.Rate >= 2 & MSRB$Year == 2019 & MSRB$Par.Traded >=500 & MSRB$Class == "PRE-REFUNDED"),]
F = MSRB[which(MSRB$Coupon.Rate >= 2 & MSRB$Year == 2019 & MSRB$Par.Traded >=1000 & MSRB$Class == "PRE-REFUNDED"),]
#SUMMARY OF PRE-REFUNDED DATA
summary(A$Yield)
summary(B$Yield)
summary(C$Yield)
summary(D$Yield)
summary(E$Yield)
summary(F$Yield)
#END OF OUTPUT FILE
